So ill run you through the whole story. My brother nicked my desktop monitor when I was away so he could use it with his laptop, whose monitor is broken. 

Once I take it back I reconnect it with the blue analog video cable he used without thinking. I later discover that this is connected to the integrated graphics card in my computer.

Previously my computer had been connected through a larger white analog video cable directly into the dedicated graphics card. 

When I booted up with the blue cable connected originally the monitor brought up a black and white screen reading something about switching graphics cards and then brought me to the desktop screen where it asked me to install some drivers for a nvidia geforce 6150 le. I did and quickly realized that this was the integrated card and is incapable of running any video games.

Upon connecting the monitor back to the dedicated card I found the screen to be unresponsive and remains on the self test feature check screen. I haven't a breeze what my dedicated card is called nor can I find it in the device manager or anywhere else for that matter

I am running a rather old dell dimension C521. 
 

 

Ask any questions you need to and I will try to answer

any help appreciated.

Hi

 

:welcome: to the Bleeping Computers.

 

Please try the below steps. 

 

Caution : Touch your hand in an unpainted metal part of the cabinet to discharge static electricity before working inside the system.

 

:step1: Remove the graphics card from slot and refit it. This will solve any possible loose connection.

 

:step2: Remove the CMOS battery and replace it with a new one.

If you are not sure about how to remove the cover, refer the official service manual.

Cheers.

 

Re-fitted the Card....Nothing.

 

I will look into getting a new battery.

 

Currently downloading drivers for my graphics card which is a SAPPHIRE HD 4550 512MB DDR3 PCI-E

To see if that is the problem.

Hi Nevinr4,

 

I suggest you to change the "Primary Video" setting in the BIOS to "PEG" and check if the discrete graphics card works properly.

 

Please let me know if you need further assistance.


Thanks and Regards,
Rajath N
